Would it be possible to test for antibodies against interferon or genetic testing to see if this is an issue, (What snps would be looked into for this and what allele would be the risk alleles?)  before taking a vaccine?  Especially for those of us with family history of vaccine reactions.  This article appears to suggest giving interferon to those having a hard time recovering from vaccine or COVID, this may be of benefit.
